What does pulmonary toxicity refer to?

Pulmonary toxicity specifically refers to the harmful effects of substances on the respiratory system, particularly the lungs. This can occur due to exposure to various chemical agents, pollutants, or environmental toxins that can damage lung tissue, impair gas exchange, or provoke inflammatory responses. Understanding pulmonary toxicity is critical in fields like environmental engineering and public health, especially when assessing the impact of air quality and occupational exposures on human health.

In contrast, other options mention organ systems unrelated to the lungs, such as the liver, heart, or kidneys, thus solidifying that pulmonary toxicity is uniquely associated with respiratory issues. This distinction is vital for professionals dealing with environmental hazards and seeking to mitigate risks associated with air quality and respiratory health.
